FLAGSTAFF — Inspectors with the U.S. Army Corps of Engineers are checking cracks found in Flagstaff's multimillion-dollar flood control dam.
Several cracks in the new 71-acre flood control basin dam in west Flagstaff were found during a recent inspection by the Arizona Department of Water Resources.
Most of the cracks are less than an inch wide.
The eastern end of the basin has an earthen dam lined with rocks and covered on top with cement. It is in the top cement where the cracks were found.
The dam is bisected by a concrete spillway, but no cracks have been found there.
The basin is designed to slow storm water runoff from residential areas in the westernmost sections of Flagstaff during major storms.
